PUMPING MACHINERY.

Specification of Letters Patent.

Patented Oct. 24:, 1916.

Application led June 5, 1915. Serial No. 32,333.

To all whom t may concern:

Be it known that I, JOHN J. BECKER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Pumping Ma` r chinery, of which the following is a speciication.

My invention relates to novel and improved pumping machinery andin particular to a mechanism for operatinga double acting plunger pump.

It is an object of this invention to construct an 'apparatus whereby the walking beams each carrying a floating gear eccentrically mounted intermediate its ends, are vertically reciprocated. The forward ends of the outer beams are connected together by means of a yoke which operates the outer plunger rod while the intermediate beam is connected at its forward end tothe inner plunger rod. The rear ends of said beams are provided with sectional gears which are kept in mesh with a stationary gear, the curvature of the sectional gears being de'- signed in such a way that the forward ends of said beams are caused to vertically reciprocate in straight lines.

Another object of this invention is to provide a series of eccentrically mounted gears actuating the beams whereby a simple and efficient construction, positive vin its operation, is provided, and the power is evenly distributed, avoiding jars and stresses in the various parts of the apparatus. f

These andother objectsof the invention will appearas the description proceeds and will be pointed out in the appended claims. In the accompanying drawings which form a part of this specification I have shown a convenient and practical embodiment of the apparatus and in which:

Figure 1 is a side elevation with parts broken away of the apparatus. Fig, 2 is a top plan view thereof.k Fig. 3 is a front elevation Vwith parts broken away, showing the,k connection of the plunger rods.

Like reference, numerals indicate like parts throughout the several views of the drawings. v 1 *In a frame 10, composed of two sections andV suitably connected with tie rod 11 and cross bar 12 at the forward upper end of the apparatus, a driving shaft 14k is suitably journaled. Power from any source is trans-f mitte'd-togpulley 15 fast `toene end of said shaft. A driving gear pinion 16 secured to the otherend of said shaft, drives a large gear 17 fastvto the countershaft 18 suitably journaled in frame 10. Secured to shaft 18 are gear wheels 19, 2O and 21, equi-distantly spaced from each other. Gears 19 and 21 operate Vthe outer walking beams A and A while gear 20 operates the intermediate walking beam B. The walking beams A and A move in unison andj carry on their forward ends in pivotal engagement, verti-kv cal rods 22 and 22, respectivelv, which at their lowerends are connected bv means of a yoke 23, to which is secured the outer plunger rod 24. The intermediate walking beam B carriesy at its forward end in pivotal-engagement yvertical rod 25 which is connected to the inner plunger rod 26, the latter working within the outer plunger rod 24, as is usual in double acting plunger pumps. The gears operating the walking beams are arranged 4in such a manner that the outer beams A and A will move in opposite direction to walking beam B so that when the upper limit of movement of beam B is reached, beams A and vA will occupv the lowest position, as shown in Fig. 1, and as will be readily understood.

The arrangement and position of the gears operating A and A are exactly alike and it'will therefore only be necessary to describe the gears operating the beam A. Assuming that the walking beams are in the positionshown in Fig. 1. it will be seen that the lower eccentric gear 21 fast on shaft 18 meshes with intermediate eccentric'gear 27 in suchv a way that when walking beam A occupies its lowest position their centers of Yrotation will lie closest together. vGear 27 is loosely mounted von a pin or rod 28 passingtransverseh7 through. beam A. A

slot 297 is cut longitudinallyv through saidy beam of a size sufficiently large to allow" gear 27 to revolve therein; The upper part. of gear 27 meshes with an upper gear 35 which is loosely mounted on stationary rod 36 transverselysecured in the upper Apart of the frame. edon rod 36 and whenbeam A is ,in the lowestposition, as shown infFig. 1, the top Gear 35 is eccentrically mount-l part of the gear is nearest to rod 3G or, in

other words,'rod 36 and rod 28 havereached the maximum-distance of separation from.

each other.

Referring now tothe gears of beam the lower; eccentric gear ,20..Seufsdz .togshaft 1.5; l

drives intermediate eccentric gear 37 loosely mounted on pin 38 passing transversely through a longitudinal slot in beam B. Gear 87 in turn meshes with upper eccentric gear 39 loosely mounted on rod 36. The size `of the gears, their position and eccentricity relative totheir respective shafts are eX- actly the same as those described in connection with beams lA and A. Their position, however, in' relation to the gears described in connection with beam A is exactly the opposite, that is to say when the upper part of lower gear 21 is nearest to shaft 18, as shown in Fig. 1, the upper part of lower gear 20 will be farthestaway from said shaft causing beam B to occupy its highest position, the distance between shaft 18 and pin 3S being the maximum separation. The upper part of upper gear 39 will befarthest away from rod 36. y

Transversely secured to thev upper part of the rear frame is a stationary rack 40. The

teethof rack 40 are adapted to engage withV a segmental gear 41 formed on the rear ends of beamsA A, A and B. The forward ends'of the beams willdescribe a rectilinear movement and will cause a corresponding vertical rectilinear movement of the pins carried by the beams on which the intermediate eccentric gearspare loosely mounted. It will be obvious from the construction of the stationary rack 40 and the segmental gear 41 that the forward end of each beam will describe a straight line while movinglin the intermediate portion of its path. This intermediate portion corresponds to approximately the length of the stationary rack 40. The structure of Fig. 1 shows a stationary rack which is materially smaller in length than the length of the movement of the forward ends of the walking beams, and consequently the extreme ends O-f the path of the movement will tend to turn slightly inwardly toward the gears. However,the ends of said walking beams are maintained in vertical straight lines, because of the lost mobev rigidly maintained in rectilinear paths.

In order to insure positive engagement of segmental gear 41y and rack 40 I have provided thefollowing mechanism: A segment of ,a ring 42 is secured to the outer ends of segmental gear 41' which encircles rack 40. Ata pointV approximately the center ofthe yring aneiilargementf43 is made providing a slot in' which a roller `44 is rotatably mountedVA on a pin passing transversely shaped'f in such a way thar'whenfthe segmental gear 41 engages rack 40 in its rocking movement, and ring 42 is oscillated, the roller 44 engaging cam 45 will insure positive engagement of said rack 40 and gear 41. In order to prevent lateral movement of the segmental gear a pair of ears 46 extending on opposite sides of enlarge-- ment 43 land engaging cam 45,-are provided. The forward ends of the beams are slotted and carry therein, spaced a slight distance from the end thereof, an antifriction roller 47 loosely mounted on a pin passing transversely through said slotted ends. The eX- treme slotted ends and antifriction roller 47 engage vertical uprights 49. The slotted ends engage said uprights'at opposite sides thereof and prevent any lateralmovement of the forward ends ofthe beams. The antifriction rollers, as well as the u'prights 49, may be dispensed with since the mechanism provided at the rear end of the beams for insuring positive engagement of the gear 41 and rack 40 will cause vertical reciprocatory movement o-f the forward ends of the beams without any assistance on the part of the uprights 49. p

The operation of the pumping'apparatus will be easily understood from the foregoing description. Power applied to pulley 15 in a clockwise direction will, through the transmission of gears 16 and 17, cause counterclockwise rotationof shaft 1S. The revolution of eccentric gears 19 and 21 to the intermediate floating gears mounted in said beams will cause the latter to vertically reciprocate the outer beams in unison and in opposite direction from the intermediate beam so that when the outer gears occupy the lowest position the intermediate beam will occupy its highest position and vice versa. It should be'noted that the gears mounted on rod 36 are not necessary for the reciprocation of the beams, in other words, the beams would operate if the upper gears mounted on shaft 36 were absent.

The purpose' of the upper gears is to cause a positive `downward movement of the beams if, foi' any reason, the plunger rods should meet with an obstruction. In such a case, if'it were not for the upper gears mounted Von rod 36, the beams4 would stay in' their upper positions and the intermediate floating gearshwould get out of mesh with the lower gears mounted on shaft 18. It is therefore seen that the upper gears cause a positive engagement between the three gears for each beam. n

'By my improved pumping apparatus I distribute the strains and stresses usually found 'in pumpingl machinery. The balancedv arrangement of the coacting` parts and the eccentric gears'elim-inate disadvantages present when a crank is used for recprocating thewalking beams.

.Other advantages will be obviousitothose skilled in the art. "It is to be understood that various changes may be made without departing from the spirit of my invention and from the scope of the appended claims. I claim: f
